Eu tenho acesso à Internet adequado e meu IP atual (no Reino Unido) é 82.47.29.14 , mas meu laptop ainda está vinculado ao servidor alemão 91.189.91.24 80 .
Mas agora não consigo fazer do-release-upgrade :
alvas@ubi:~$ sudo do-release-upgrade -d
Checking for a new Ubuntu release
Err Upgrade tool signature

Como devo resolver esse problema para que eu possa do-release-upgrade ?
